To all whom. it may concern.-

Be it known that I, IRA C. MCOLENTHEN, a citizen of the United States,residing at Hebron, in the county of Porter-and State of Indiana, haveinvented certain new and useful Improvements in Smoke-Consumers, ofwhich the following is a specification.

My invention relates to smoke-consumers for boilers; and its primaryobject is to providea simple and inexpensive device of the characternamed which will effectively consume the carbon contained in the smokein the fire-box, thus materially increasing the combustion and savingfuel, and also avoiding the injurious effects of the soot ordinarilycontained in the smoke from locomotive or stationary boilers.

The invention utilizes a combination of dry steam, gaseous vapors, andhot air to efiect the purpose in view, and an apparatus of novelconstruction which will be fully described hereinafter in connectionwith the accompanying drawings, which form a part of this specification.

In the drawings, Figure 1 is a vertical sectional view of a boilerprovided with my invention. Fig. 2 is a central vertical section, on anenlarged scale, of that portion of the ipparatus which is located withinthe fireox. retort of the device, and Figs. 4., 5, and 6 are detailperspective views of parts of the retort.

Referring to Fig. 1 the reference-numeral l designates aboiler of theusual or any preferred construction, having the fire-box 2, tubes 3,andsteam-dome 3*, From the dome 3 a steam-pipe 4 extends rearward,connecting by a vertical pipe 5 and a horizontal pipe 6 with theinterior of the fire-box 2. The pipe 4 may be support-ed in any suitablemanner, as by a bracket 7, projecting above the boiler. The inner end ofthe pipe 6 is bent downwardly to support the retort of the apparatuswithin the firebox at an angle of approximately fortyfive degrees.

8 designates an oil-tank supported adjacent to the steam-pipe 6, as bybrackets 9, and having a downwardly-inclined spout 10, communicatingwith an enlarged portion 6, secured to pipe 6 and forming avaporizingchamber therein. This spout 10 is provided with a cook orvalve 11 to control the flow Fig. 3 is a view in perspective of the anasbestos wick 33 below the retort.

of oil to the vaporizing-chamber 61, and the tank is provided with afilling-funnel or oilinlet 12. Below the pipe 6 is suitably sup ported,asby hangers 13, Fig. 1, a burner comprising a frame and an asbestoswick 14 therein adapted to be saturated with kerosene or likeinflammable liquid and lighted to generate the initial charge of gas, aswill be further explained hereinafter.

The construction of t he retort and its casing will now be described.The upper section of the casing of the retort consists of aconcavoconvex plate 15, formed with a central opening surrounded on itsouter side by an internally-threaded annular flange 16 and on its innerside with a projecting collar 17. The threaded fiangelti receives theexternallythreaded end 19 of the pipe 6, while the inner collar 17serves as a guide for-the stem of the retort, as hereinafter described.15. is formed at one side with a lug 20 and at a plurality of pointsprovided with openings 21, into each of which is secured an an gle-pipe22, serving as an inlet for air. The under edge 23 of the plate isoutwardly flared orbeveled to direct the vapors downward and act as aspreader to distribute the vapors over the coal in the fire-box. Thelower plate 24 of the casing also consists of a concavo-convex platearranged reversely to the plate 15, so that the two plates when securedtogether constitute a hollow chamber 26 to contain the mixer. This plate24 is formed with a lug 27 and is recessed at the point 28 to-adapt thelug 27 to fit against the .lug of the upper plate 15, to which it issecured by bolts and nuts 29. Plate 24: is smaller in diameter than theupper plate 15, and a passage is formed at the edge thereof to permitthe escape of the gases discharged into the casing formed by saidplates. The plate 24 is also formed with a central opening or bearing30, surrounded on its under side by a collar 31, which is preferablygrooved annnlarly for the attachment thereto of a burner com prising ahanger 32 for supporting The mixer comprises a hollow sphere,"consisting of two selnispherical sections 34 and 35, each formed at itslower side with a solid semicircular lug 36 and at its opposite sidewith a hollow semicircular projection 37. 'When the The plate twosections '34 and are brought together,

' as shown in Fig. 2, the lugs 36 form-a circuperforate, as shown, whilethesection 35 is formed with a series of parallel slots 38, ex-. tendingalmost entirely across the section for the escape of steam and gas intothe chamber 26. These slots may be formed across the plate, as shown inFig. 2, or lengthwise thereof, as illustrated in Fig. 5.

The operation of the apparatus constructed as above described is asfollows: The cook 11 is opened to allow oil to pass into the jacket 6,and the wick 14c is lighted to generate a vapor within the jacket 6before steam is ad- I mitted. By means of a valve steam is admitted intothe pipes 5 and 6. The commingling of steam and gas-with the hot airwhich enters the pipe 22 materially increases the combustion andconsumes the carbon in the smoke, thus effectually accomplishing thepurpose in view.

Many of the details of construction herein shown and described may bevaried without departing from the spirit of the invention. For example,the means shown for suspending or supporting the wicks may be changed ormodified atwill and other minor changes may be resorted'to.
